System and Method of Fast Roaming in an Enterprise Fabric Network

2. The system of claim 1, wherein the controller is configured to update the database with a corresponding client identifier and a VNID entry with the new routing value corresponding to the first network device or the second network device based on information received from the first network device and second network device.

3. The system of claim 1, wherein the controller is configured to find and update all virtual network identifiers based on the correlation.

4. The system of claim 1, wherein the controller is configured to generate a notification message to send the new routing value to each of the first network device and the second network device, wherein the notification message comprises the client identifier, client-MAC address, a client-IP address, and at least one of a Level-2 end-point identifier (L2-EID), a L3-EID, a VLAN associated value, a VXLAN associated value, Switch Integrated Security Feature (SISF) associated value, enterprise fabric control plane data, and hosting-tracking database data, associated with the client.

5. The system of claim 4, wherein the controller is configured to send, to border nodes of the enterprise network, the notification message as an unsolicited SMR (solicited map server request).

6. The system of claim 1, wherein the controller is configured to provide, at least, the new routing locator to nodes or border nodes in the enterprise network.

7. The system of claim 1, wherein the controller comprises a network switch.

8. The system of claim 1, wherein the at least one parameter is derived from a reassociation frame received in the enterprise network.

9. The system of claim 1, wherein the at least one parameter is included in, or derived from, a packet received in the enterprise network after a virtual client has been reorchestrated from a first location associated with a network device to a second location associated with the first network device or the second network device.

10. The system of claim 1, wherein the controller is coupled to wireless LAN controller.

11. The system of claim 1, wherein the first network device and the second network device are each configured to update client-MAC or client-identifier binding associated with L2-VNID or L3-VNID based on a notification message that includes the new routing locator sent to the respective network device.

12. The system of claim 11, wherein the first network device is configured to create an away entry for an away table based on the notification message sent to the first network device or the second network device.

13. The system of claim 11, wherein the first network device or the second network device is further configured to learn one or more IP address associated with the client from the notification message sent to the respective network device.

14. The system of claim 11, wherein the first network device or the second network device is further configured to learn one or more IP address associated with the client from traffic received from the client.

15. The system of claim 11, wherein the first network device or the second network device is configured to send a registration message to the controller to notify the controller of <client-IP, L3-VNID> to a RLOC mapping determined from the traffic received from the client.

16. The system of claim 1, wherein one or more notification messages carry the new routing locator to the first network device and the second network device, the one or more notification message comprising <client identifier, L2-VNID> to RLOC mapping and/or <client identifier, L3-VNID> to RLOC mapping.

17. The system of claim 1, wherein the client comprises a virtual machine or VM host.
